External rotor motor compact axial Cooling Fans:
Due to the sickle blades, cooling fan makes the high flowing efficiency. Compared with the fans with standard blades which in the same size and with the same speed, this fan line has higher air flow and lower noise, but with only shortness that the max static pressure it can attain is relatively lower. However, this shortness caters for the requirements of modern refrigerant equipment.
In addition, this line blade is solely punched into mould and then welded onto the motor rotor. Mould of making blade in this way is comparatively in smaller size, so that fans of this line has more competitive price compared with fans with standard blades and with external motor drive. Fans of this line are preferential recommended cooling fan by us.
